CKSH-DT (branded on-air as Radio-Canada Estrie) is the Télévision de Radio-Canada owned-and-operated television station, serving the Estrie region of the Canadian province of Quebec that is licensed to Sherbrooke. It broadcasts a high-definition digital signal on VHF channel 9 from a transmitter in Orford.
Owned by Société Radio-Canada, its studios are located on Boulevard Industriel/Route 220 and Boulevard de Portland in Sherbrooke. This station can also be seen on Vidéotron channel 10 and in high definition on digital channel 602.
The station first signed on September 19, 1974. As a privately owned station, CKSH basically functioned as a semi-satellite of CBFT in Montreal due to not having alternative non-network sources of programming available. The station had been owned directly by Cogeco prior to the latter's majority acquisition of TQS (now V), to which Cogeco contributed its existing local stations. Radio-Canada took editorial control of the station's news programming in 2002, although it currently shares a studio with former TQS sister station CFKS-DT.
In September 2007, Radio-Canada announced that it would not renew its affiliation agreement with its three Cogeco-owned affiliates — CKSH, CKTM-TV in Trois-Rivières and CKTV-TV in Saguenay — after their then-current agreement expired in August 2008. An application to directly acquire the station was filed by Radio-Canada on April 25, 2008, concurrently with Cogeco's proposed sale of TQS to Remstar Corporation. The transaction was approved by the CRTC on June 26, 2008.
Now that Radio-Canada owns the station, it intends to increase local programming and to relocate all of its radio and television facilities in the region into an integrated production centre.
Digital television and high definition 
After the analog television shutdown and digital conversion, which took place on August 31, 2011, CKSH has shut down its analog transmitter at midnight on September 1, 2011, and started digital broadcasts on its old analog channel number, 9. However, through the use of PSIP, digital television receivers will display CKSH's virtual channel as 9.1.
